\n" ); document.write( "First, let's compute to have an ave. of 70:
\n" ); document.write( " $\"%282%2F3%29MT%2B%281%2F3%29FE=70\"$
\n" ); document.write( " $\"%282%2F3%29%2848%29%2B%281%2F3%29%28FE%29=70\"$
\n" ); document.write( " $\"%2896%2F3%29%2B%281%2F3%29%28FE%29=70\"$
\n" ); document.write( " $\"%281%2F3%29FE=70-%2896%2F3%29=70-%28cross%2896%2932%2Fcross%283%29%29\"$
\n" ); document.write( " $\"%281%2F3%29FE=70-32=38\"$ , cross multiply
\n" ); document.write( " $\"FE=38%2A3=114\"$
\n" ); document.write( "Next, ave. of 79:
\n" ); document.write( " $\"%282%2F3%29%2848%29%2B%281%2F3%29FE=79\"$
\n" ); document.write( " $\"%2896%2F3%29%2B%281%2F3%29FE=79\"$
\n" ); document.write( " $\"%281%2F3%29FE=79-%2896%2F3%29=79-%28cross%2896%2932%2Fcross%283%29%29\"$
\n" ); document.write( " $\"%281%2F3%29FE=79-32=47\"$ , cross multiply
\n" ); document.write( " $\"FE=47%2A3=141\"$
\n" ); document.write( "Therefore, the Final Exam should be in the range of $\"highlight%28114-141%29\"$ to have an average of 70-79 inclusive.
